You

9 o'clock, December, 24th.

"Where are you, Dave ? We have been looking for you for one week ! I miss you. Why aren't you here ? Why did you leave me alone ? Come back, please..."

11 o'clock, December 23rd.

It was a few days before Christmas. School was over and everybody was looking for presents to give to their family or friends...Everybody, apart from Mrs.Smith. She called me on the phone on the 23rd December, it was eleven o'clock in the evening.

"-I'm sorry to disturb you so late but my son disappeared a few hours ago and I thought that you would like to know...", Mrs.Smith told me in a desperate voice. Of course I wanted to know. But the news came as a shock to me. During one week, the longest week in my life, we were looking for you. The whole town was looking for you, but we were very sad because the police thought that you were dead, Dave. I hope they are wrong. Really.

 "You are not in the river, you are not in the lake, you are not in the forest, so where are you ?

-Just here ! Dave ?

-But where were you ? Why didn't you call me ?

-I don't know what happened but I'm back now, don't worry. I have to go home, mum is waiting for me.

-Yeah, but call me, and not in a week !

And he just left. I didn't know that he would never come back."

"At midnight. Mrs.Smith called me. Again. They had found him. Dead for one week."
